The first film to feature Stanley Myers' "Cavatina" theme (later re-used to more famous advantage in 'The Deer Hunter').
All the paintings, 7 abstracts, 3 London river scenes, 2 impressionists and a portrait seen in the film were actually done by David Hemmings who'd spent a little time at Epsom School of Art but was mainly self taught.
Last cinema film of Emlyn Williams.
The only screenwriting credit of Professor George Bluestone, author of a famous book about the art of adapting novels for the cinema. It is believed that the actor Al Lettieri did a rewrite on the script.
